Yes he always claims that can try same phone unlimited times and only be charged once, but always have to appeal and send requests for credits to be returned

if you say so.. but so many phones had this done and none relocked explicitly due to switching csc from TMK to TMB!! Only nuance is it has been observed that sometimes relock when using simple mobile or straight talk US MVNO carriers

Ok Sir, this case is that it has been locked again, Is was worked well for almost a month, the operator is in Cuba where there is only one, it is not the case that one of the USA was used, maybe they touched the Device Unlock app, But I do not know why they did not tell me, Now my question is this: I can repeat the Unlocking and Paying again. Best regards. bedel

They changed the firmware from METRO to T-MOBILE. Different unlock app.
